Very easy to use, nice and crisp sounds. And sufficient volume, (where others are lacking), and very pleasant to look at!

Well done for simple practice

Great for keeping track of how long you are practicing. It almost feels like a real metronome. Well done.

Not accurate

I was starting to wonder why scales were easier when playing with this metronome than my korg... Today I set them both to 60 and compared them to a stopwatch. The korg was completely accurate, while this one was slow, and not even completely steady! I'll be looking for a more accurate metronome app now.
